Re: Outdoor rated Cat5 required?
said by wwwires :
Is there any type of spray or paint that you could apply to the exposed cable to seal it from the elements?
I am going to say no?. Depending on what the compound You are using to do this contains?, it may start to break down the jacket of the CAT5 even faster than what the UV rays of the sun can?. I have tried to use different substances over the years to seal coax connectors, and some worked and some did not?. The stuff that worked was fine for sealing short distances, but You would not want to try and apply it to a few feet of CAT5 cable, as it would be both difficult and messy.I have found that most standard CAT5 cable does fine outside, but it is very prone to cracking at bends and any place You have squeezed it or applied pressure?, like using a zip tie to attach it to a tower. I will admit that once this happens, it becomes a big bendable straw  , and water will follow it right to the end of the cable, and as mentioned before, run out all over whatever is there.

Fort Frances, ON | Google for liquidtight flexible conduit. Only seal one end waterproof and stuff fibreglass insulation in the other end to keep bugs out.
Black poly pipe works good too. |

| Yea, we've used the sealtite (what we call it) constantly on some of our transformer banks. I was looking to spend less money per install, but don't want to jeopardize the integrity of the cabling either. We used to purchase the flooded UTP for under $100/1000' as others have stated, but now we can't come close as most vendors are out.
Are there that many more people using it now?
I'll use the CMX since I do not see the need for the flooded cable except on towers, etc. I'll contact Graybar on our next purchase though, with the #'s listed above. Maybe they can find it this time.  |

I'm still using gel filled, but as prices keep going up, I'm investigating using heat shrink tubing for the outdoor portions on cheaper cat-5. I know it is available in bulk roles and weather proof. |

Anyway, in your first post you were only talking 3 or 4 feet. Gel-filled may be over-kill but the outdoor stuff with the gel filling usually has the tougher jacket as well for direct burial. The main concern I have is for rodents chewing through the wire. Seems they don't like the gel any more than we do and stop chewing when they get a taste of it.
You could also consider a short piece of soft copper tubing with the black poly jacket. If you use the bare stuff, the green oxide would stain the house. |

| I'll be satisfied with the CMX outdoor jacket for a little over $100/1000', but don't see how we were paying less than that 3 months ago for the gel filled. It just doesn't make sense.
We have a pop where we have to use about 75' of the sealtite conduit due to rodents. It's a rice mill, and there are power cables that are chewed through and hanging on by a few strands, so I know I need the metal ring filled sealtite there, not just the plastic. |

Let's go on strike and not buy this stuff anymore It's kind of funny that one year ago we were all whining about the cost of CPE's, now this. I continue buying the HomeDepot stuff, it costs just as much as the others listed here by the time you figure taxes and shipping. |

It would be better if we could get it in 1000' boxes/spools. I really like the HD stuff, it's easy to work with, it holds up very well, and it's readily available. As I said, by the time it's all said and done, it costs just as much as the other non-flooded cable. However, I'm always looking for better options. |

The cost of CPE's has dropped to the point that anyone who says they can't make any $$ in this business is crazy!. While most of You do not like Raylink, I am loving the stuff more and more every day!. I just bought 2 brand new CPE's in the box for $13.00 each! Talk about making $$ from day 1!. I also just bought a new Deliberant 2700 connectorized unit for $67.00!, and it was brand new also. Ebay is a great place if You are persistent?.
Your second thought about the cable is the same way I think also?. The other cool thing is that it is there when I need it, and I am never stuck waiting to do installs on the UPS guy. I also do not have to shell out any extra cash to buy spare rolls "Just in case", as it seems that most times when I do that, it is $$ that just sits there and does nothing?.

The worst part is that NOBODY else carries outdoor CAT5 in my neck of the woods, and quite frankly, I think I'm the only one that buys this stuff from HomeDepot here |

| Yea, that's why I was so shocked none had any. I thought Stealthwave done bought'em all out. lol
I've got some coming now, so I'll use these 2 spools. I still have a few 100' of the flooded direct burial cable which I'd like to save.
We're adding a new pop, and only have 125' of the sheilded flooded cable, so I might have to use some non-shielded temporarily. |

Something to think about. Even though only 3 of cable is "exposed" to the weather the reality is the whole cable is. Remember that once moisture enters the cable it will travel up the space between the copper and the pvc meaning the actual point of corrosion could be anywhere on the cable. So the rationalization of only 3' being outdoors making it not worth it really doesn't fly.
That said we use the outdoor home depot stuff most of the time as proper install in a dryer climate will prevent water from causing the problem I described. The only places where you might consider flooded cable for CPe is on the ocean.
